Remapping

[Woody100]

Morning all

Today's Sunday morning question !

My car was remapped back in 2004 by a previous owner but since then a couple of extra mods have been done like Gruppe M induction kit and a Eisennman exhaust so my question is should I have it remapped again ?
And has anybody used Torque Development International as they have a great write up in this months BMW performance mag and they are only 20 mins down the road

If it is a live remap then yes it will be worth doing, if it is a generic map then it is tuned for the OEM equipment and of no benefit to you, but don't expect a massive improvement, that said the driveability should be improved (smoothness etc)

Mapping is a funny one, I have had all sorts of funny statements from people, the truth is that nearly all forms of mapping are very much the same, rolling road uses a lot of the same software that obd mapping uses, yes running a car on a rolling road will always get better results but I was annoyed with people saying things about it that made it sound like some sort of hoax, I even had one bloke say that it's not remapping because you can't prove your figures, 2 days later I saw him bolting on an air filter to a customers absolute pile of vw camper no doubt with all the power claims that come with it. At the end of the day it all comes down to what your willing to spend, at speed will charge £460 for dyno mapping and when I took mine down there to see what my obd remap got it was 1hp over the suggested figure. He even said to me that with naturally aspirated engines it's hard to squeeze more out of them and a dyno run would probably only produce 2-4hp more than an obd tune. Stay clear of second gen maps tho they are just a standard map that will run on everything but with very little improvement, a map (either obd or rolling road) will cater for air filter and exhaust but one will get more hp, for an extra 300 quid.

I think you hit the nail on the head, there are too many variations on a theme with some standard re-maps, my mate had his civic done, and they downloaded three maps before getting one that made a difference to the car, truth is if its not a live re-map it needs to be done by someone who knows what they are doing or an already proven map from a named company

It's such a problem with all the people selling magic boxes on the internet and what not it makes people like me catch the flack, suppose it's a case of everyone doing the research and deciding how much they want to spend, and I guess realising that bmw engine are already pretty maxed for power as standard

You still doing the remaps Dan ?

 

[Grimstead]

I do mate yes, but if you want rolling rd stuff I don't know a lot about torque developments so can't say, I've moved to a new programming company now and everyone that I mapped has been given an updated map as their software is a lot better than the old company I was tide too. I didn't contact you because I knew you'd changed cars, how's the z3.0 anyway?
